Abstract

Systems of photonic crystalcavities coupled to quantum dots are a promising architecture for quantum networking and quantum simulators. The ability to independently tune the frequencies of laterally separated quantum dots is a crucial component of such a scheme. Here, we demonstrate the independent tuning of laterally separated quantum dots in photonic crystalcavities coupled by in-plane waveguides by implanting lines of protons which serve to electrically isolate different sections of a diode structure.
